Halogenbonding triggers activity: Increasing binding affinity was observed for a series of covalent human Cathepsin L inhibitors by exchanging an aryl ring H atom with Cl, Br, and I, which undergo halogenbonding with the CO group of Gly61 in the S3 pocket of the enzyme. Fluorine, in contrast, strongly avoids halogenbonding (see scheme). The strong distance and angle dependence of halogen bonding
The invention relates to a compound of formula (I)
wherein A and R1 to R7 are defined as in the description and in the claims. The compound of formula (I) can be used as a medicament.
